Specification of Letters Patent.

Applicationfiled June 29, 1910. Serial No. 569,465.

To all whom it may concern:

Be it known that we, LLOYD B. HALLOGK and GEORGE T. KEEN, citizens of the United States, and residents of the city of New York,

borough of Manhattan, in the county and State of New York, have invented a new and Improved Engine-Starting Device, of

which the following is a full, clear, and eX-v act description.

The object of the invention is to provide a new and improve engine starting device,

more especially designed for use on internal .or leaving the seat.

For the purpose mentioned use .is made of "a grooved shaft and provided with a sleeve for turning the shaft in one direction to r0 tate the-engine shaft.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in

which similar characters of reference indicate corresponding parts in all the views.

. construction, is provided on its shaft B with a fly wheel (3, having a bevel gear wheel I) secured or formed thereon, and a pinion E is adapted to meshwith the said bevel gear wheel D, and the pinion is secured on the lower end of an upwardly-extending shaft F mounted to turn in a bearing G, held on a rock shaft H, journaledin suitable bearings I mounted on the chassis or frame of the 'motor vehicle on which the device is used.

The shaft F is provided on its peripheral face with a spiral groove F, into which projects the inner end of a screw K, secured on the lower end ofa sleeve L, mounted to slide on the upper end of the shaft F. In order to move the sleeve L lengthwise on the shaft F, use is made of a handle N, provided with a bearing N loosely engaging the upper end of the shaft F, and on the said bearing N is arranged a screw N extending into an annular groove F formed on the shaft F. Thus by the arrangement described, the sleeve L can be moved up or down on the shaft F. On the bearing N is fulcrumed a spring-pressed pawl O, engaging aratchet wheel 0' secured to or formed on the upper terminal of the shaft F, so that the sleeve L is held against turning when sliding it down on the shaft F by the operator moving the handle N in a downward direction, and the sleeve L is free to rotate on the shaft F when moving'the sleeve upward on the said shaft.

By reference to Fig. 1, it will be noticed that the spiral groove F has its pitch gradually decreasing from thetop downward, so that when the sleeve L is in an outermost position and is pushed downward by the operator bearing down on the handle N, then the shaft F is turned, and its pinion E in mesh with the gear wheel D rotates the shaft B to start the engine A. When the sleeve L is drawn upward it rotates on the shaft F, as

the pawl O and the ratchet wheel 0 now permit such movement, while the handle N is held against turning by-the operator.

-W;hen the device is not in use, it is swun forward into the position shown in dotte lines in Fig. l, sothat the pinion E is outv of mesh with the gear wheel D, but whenever it is desired to make use of the device for starting the engine, then the operator takes hold of the handle N and swings the same forward and with it the shaft F, so that the pinion E moves into mesh with the bevel gear wheel D. The operator now pulls-the sleeve L outward and then bears down on the handle N, so that the shaft F' is turned torotate the pinion E, the gear wheel I), fly wheel C and shaft B, to start the engine A in the usual manner. By having the spiral groove F decreasing in pitch from the top downward, it is evident that a gradually increased speed is given to the shaft F at the time the sleeve L is pushed downward, so that the operator can easily start the ,rotation of the engine shaft .13.

It is understood that the device is mainly used on internal combustion engines having multiple cylinders, so' that it requires but a partial rotation of the shaft B to bring the engine into starting position, and by giving the spiral. groove F a number of convolutions, it is evident that the shaft F is turned several times during the downward movement of the sleeveL, to cause the pinion E to turn the gear wheel D, fly

wheel 0 and the shaft B the desired distance for starting the' engine. Thus. the pinion E can be made comparatively small relative to the gear wheel D, and hence but little physical exertion is required on the part of the operator to properly start the engine.

" The device is very simple and durable-in construction, is composed of comparatively 'few' parts. not liable 'easily to get out of ing'thelatter, and a rocking bearing in which the pinion shaft is mounted.

'2. An engine starting device, comprising a spirally. grooved shaft mopnted to turn and to rock, a gearing for connecting the saidshaft with the engine shaft, and a manually controlled sleeve mounted toslide on the said spirally grooved shaft and having a member projecting into the spiral groove of the said spirally grooved shaft.

3. Anengine starting device, comprising a gearWvh-eel on the engine shaft, a pinion adapted to" mesh with the said gear wheel,

a pinion shaft carrying the said pinion, a manually controlled member slidably connected with the said pinion shaft for rotating the latter, and a rock shaft on which the said pinion shaft is mounted to turn and to rock for throwing the said pinion in and out of mesh with the said gear wheel.

4. An engine starting device,'-comprising a gear wheel on. .the engine shaft, a pinion adapted. to mesh yvith the said gear wheel, a pinion shaftcarryingthe said pinion, a sleeve slidably connected with the said pinion shaft to rotate the latter, a handle, a pawl and ratchet mechanism connecting the said handle and sleeve to hold the latter against rotation when moving it lengthwise of the pinion shaft in one direction and to allow the sleeve to rotate during the return movement.

5. An engine starting device, comprising a shaft .having a spiral groove, a sleeve mounted to slide on the said shaft and having .a member engaging the said spiral groove, a handle for moving the said sleeve lengthwise on the said shaft, a gearing for connecting the said spirally grooved shaft the engine shaft and adapted to be engaged by the said pinion, a shaft mounted to rock,

and abearing held on said rock shaft and in which the said spirally grooved .shaft is mounted to turn.

7. An'engine starting device, comprising a shaft having a spiral groove, a sleeve mounted to slide on the-said shaft and hav-' groove, a handle for moving the said sleeve lengthwise on the said shaft, a pawl and ratchet mechanism connecting the said handle with the said spirally grooved shaft,

a pinion 'on the said shaft, a gear wheel on the engine shaft, and a bearing mounted to rock and in which the said shaft is mounted to turn for throwing the said pinion in and. out of engagement with the said gear wheel.
